</div>

this looks dynamic like  
class vi has 2 subjects  
class vii has 2+ subjects

then  
each subject have dynamic number of multiple sections with questions

```
List<WebElements> screen1 = driver.findElements(By.className("buttons in list view"));
for (int i=0;i less then screen1.size();i++){
   screen1.get(i).click(); // this takes us to screen 2 for first class like class vi
   List<WebElements> screen2 = driver.findElements(By.className("get all subject of class v1"));  
      for (int j=0;j less then screen2.size();j++){
             screen2.get(j).click();
                List<WebElements> screen3 = driver.findElements(By.className("get all question of class v1 subject 1"));  
                        for (int k=0;k less then screen2.size();k++){
                                        screen3.get(k).click(); 
                                       // now we reached to questions u can perform verification here                                        
                       } // end of screen 3 for loop

          } // end of screen 2 for loop
}// end of screen 1 for loop

```

Challenge here is we need a single locator that build list of all WebElements on a page we need to click.

@amitjaincoer191,  
Its working as expected but there is one problem, It is picking random list item from every screen while it should be sequence.  
Please help me out to pick the item from list one by one not randomly.
